The FGGA is compared to a CO2 standard gas approximately every two weeks.
1Accuracy is given in terms of the maximum deviation between FGGA and the CO2 standard, combined with the 2.5 ppm uncertainty the standard.
2Instrument presision is determined as the standard deviation determined during the standard measurements.

The full specifications of the Fast Greenhouse Gas Analyzer are found here.
